Oral impression transfer device and its loading and unloading method

Abstract

The invention discloses an oral impression transfer device which is characterized in that the upper part of an impression transfer body is positioned above the lower part of the impression transfer body and fixedly connected with the lower part of the impression transfer body; an inner cavity is formed between the upper part of the impression transfer body and the lower part of the impression transfer body; a worm wheel is arranged in the inner cavity and meshed with a worm rod; the two ends of the worm rod penetrate out of the upper part of the impression transfer body and the lower part of the impression transfer body; an impression transfer screw rod is in threaded connection with the inner cavity of the worm wheel; a positioning boss is arranged at the bottom of the lower part of the impression transfer body. According to the oral impression transfer device, the structure with the worm wheel and the worm rod is adopted, and the impression transfer screw rod capable of rotating on the lingual side (or the buccal side) is designed, so that the problems of small opening degree, difficult vertical rotation of the impression transfer screw rod, inconvenient doctor operation and inaccurate impression extraction are effectively solved; the structure design is simple and reasonable, the manufacturing cost is low, the operation efficiency of doctors is greatly improved, the patient-hospital disputes caused by inconvenient operation are avoided, the pain of patients is relieved, and the development of oral implantation technology is promoted.

Description

technical field [0001] The invention relates to the field of oral implant technology, in particular to an oral impression transfer device and a method for loading and unloading the same. Background technique [0002] Implant denture restoration includes a series of processes such as implant plan formulation, implant placement, implant transfer impression, denture production, try-in and insertion, and maintenance after completion of implant restoration. Accurate impressions and working models of implant relationship transfer are the basis for denture production. [0003] Dental implant surgery It is very important to make restorations according to the shape of the teeth of the surgical object and to make the restorations in the correct position. Therefore, the impression material is used to print out the shape of the teeth of the surgical object to make an accurate tooth model, and the most accurate restoration is made with this model for the actual surgery. [0004] In the...
